In the WebUI, when trying to generate a new diagnostics file through Monitor > Diagnostics the message "Another diagnostics process is currently active, do you want to abort it?" is displayed, as shown below:
Clicking Yes or No does not generate any action on the SSLV appliance.
Then, the message keeps appearing.
An SSH session (same user) created a diagnostics file and is still active on the appliance.
There are two ways to solve the problem:
and click on the plus button
and create a new user with the Manage Appliance role.
Then run the diagnostics normally with the new user you created.
